Excellent Quality and Performance Boost
The K&N High-Flow Original Engine Air Filter is fantastic! Installation was simple, and it fits perfectly. I’ve noticed a slight improvement in throttle response and overall engine performance, which is great. The filter feels very durable, and I love that it’s washable and reusable — a cost-effective choice in the long run. Definitely a high-quality product that I’d recommend to anyone looking to improve airflow and maintain engine efficiency.

This is a great filter, if you know the product then you know. Increase horsepower, increased fuel economy. Obviously it's easy to install. And this is the best price you can get for it shopping anywhere.

Sounds good
Put this in my 2020 Nissan Armada. Not much of a difference on performance or gas mileage that I noticed but the intake/induction noise is more pronounced so it sounds more sporty. There could be performance gains, but I can’t tell. Take that as you will.

K&N surprise !
I needed a new air filter for my 2012 QX56, with 5.6liter V8 that eats escalades, LOL . I could tell that fuel mileage had dropped just a bit over last spring. So I opened the filter case and yeah it was quite dirty. So I was looking at the Wix air filter listed here on amazon for a QX, but it doesn't have that 'notch' in the corner of the filter so I was afraid to order it. Then I saw the good price here on the K&N filter. I had not tried a K&N air filter before, so why not. It was here in three days and It fit perfectly. The K&N has a larger filter area where the stock filter was plastic for a good two inches of filter area. Immediate difference. The fuel mileage is up to 19 mpg, consistently! I didn't buy the QX for fuel mileage, mostly cause it is built like a tank. That K&N will let the 5.6 'sing' a little too. It sounds good on acceleration,where it was quite muffled before. I like the idea that the engine is getting more air, and the boost in fuel mileage is a bonus, if I can keep my foot out of the accelerator. It is a well built made in USA air filter. I am glad I tried it. I think you will notice a difference for the better too! Thanks K&N.
